Abstract: Various embodiments of communication and validation methods and systems using RFID components, systems and technology to implement wide-ranging applications. In an embodiment, a combination of one or more RFID tags detected by an RFID reader is communicated to a network server for comparison with a pre-programmed database of data, messages or instructions corresponding to various combinations of RFID tags. Upon matching the detected combination with its corresponding data, message or instruction, the network server communicates the data, message or instruction to at least one human interface device for review by a user of the system. An embodiment may be directed towards a system for inventory management by providing to users of the system an alert when the inventory levels for a specific product within a defined zone fall below a predetermined level and confirming said low stock alert within the defined zone by a secondary validation method.
